HESI A2 Vocabulary 2023

Correct Answer: A

Rationale: The correct answer is A: Ripple. In this sentence, 'undulate' is used to describe a smooth, wave-like motion of the muscles, which aligns with the meaning of 'ripple.' The word 'undulate' implies a continuous and flowing movement, resembling the gentle and rhythmic movement of waves. The other choices, shake, flatten, and unknot, do not capture the specific fluid and continuous motion described in the sentence. 'Shake' implies a more abrupt and irregular movement, 'flatten' suggests a completely different action of making something flat, and 'unknot' refers to the action of undoing a knot, none of which fit the context of the sentence.

Correct Answer: D

Rationale: The correct answer is D: Authorized. In this context, "sanctioned" means the professor gave official permission or approval for the field trip. This is evident from the sentence structure where the professor is allowing or permitting the trip. Choices A, B, and C are incorrect because they do not align with the meaning of the sentence. "Organized" (A) implies planning, "Deterred" (B) means discouraged, and "Neglected" (C) means ignored, none of which fit the context of the sentence.

Correct Answer: B

Rationale: The correct answer is B: viral infection. HPV stands for Human Papillomavirus, a common sexually transmitted infection that can cause genital warts and certain types of cancers. This abbreviation specifically refers to a type of viral infection, not a blood condition (A), heart rate (C), or therapy (D). It is important to understand medical abbreviations to accurately interpret and communicate health information.

Correct Answer: B

Rationale: The correct answer is B: stretch. When tubes distend, they expand or elongate due to internal pressure or force applied. This leads to stretching of the tube material. Flexing (choice A) implies bending, which is not the primary response when tubes distend. Solidifying (choice C) means to become solid, which is the opposite of what happens when tubes distend. Collapsing (choice D) is the opposite of stretching and occurs when tubes lose their internal pressure or support, leading to a decrease in size.

Correct Answer: A

Rationale: The correct answer is A: Makes a suggestion about. In the sentence, 'suggests that' indicates that the study is proposing or indicating a possibility that vaping may have certain effects. It implies a tentative conclusion rather than providing concrete evidence (B), subtly alluding to an idea without explicitly stating it (C), or advocating for a specific course of action (D). Therefore, 'suggests that' aligns best with the idea of presenting a suggestion or implication, making choice A the most fitting description.
